脱水症状
脱水症状 in 30 Sekunden
- A formal medical term for dehydration symptoms, used widely in Japanese health warnings and news.
- Composed of four kanji: removal (脱), water (水), symptom (症), and state (状).
- Commonly paired with the verb 'ni naru' (to become) or 'okosu' (to cause).
- Crucial for navigating Japanese summers and discussing health safety with doctors or coaches.
The Japanese term 脱水症状 (だっすいしょうじょう - datsuishoujou) is a critical medical and everyday noun used to describe the physiological state of dehydration. To understand this word deeply, we must look at its four constituent kanji characters. The first character, 脱 (datsu), conveys the idea of removal, shedding, or escaping. The second, 水 (sui), is the familiar character for water. Together, 脱水 (dassui) literally means the loss of water or dehydration. The final two characters, 症状 (shoujou), mean 'symptoms' or 'medical condition.' Therefore, the full term refers specifically to the 'symptoms resulting from the loss of water' from the body.
- Clinical Context
- In a medical setting, doctors use this term to diagnose a patient who has lost excessive fluids due to heat, illness (like vomiting or diarrhea), or insufficient intake. It is a formal, precise term.
激しい運動の後は、脱水症状に気をつけなければなりません。
(After intense exercise, you must be careful of dehydration symptoms.)
In Japan, this word becomes ubiquitous during the humid summer months. Because Japan experiences extreme humidity and heat (often referred to as mushi-atsui), the risk of heatstroke (熱中症 - necchuushou) is high. 脱水症状 is often the precursor or a primary component of heatstroke. You will hear weather presenters, sports coaches, and teachers constantly reminding people to drink water to avoid these symptoms. It is not just a 'thirst' word; it implies a physical decline or a dangerous state requiring intervention.
- Public Safety
- Public announcements in parks and train stations often use this term during 'Heatstroke Alerts' (熱中症警戒アラート) to advise the elderly and children to stay hydrated.
祖父は脱水症状で病院に運ばれました。
(My grandfather was taken to the hospital due to dehydration symptoms.)
Culturally, there is a strong emphasis on 'suibun hokyuu' (fluid replenishment) in Japanese schools and workplaces. If you look pale or dizzy, someone might ask if you are experiencing 脱水症状. It is a word that bridges the gap between everyday concern and medical emergency. Understanding this word helps you navigate Japanese summers and health-related conversations with the appropriate level of seriousness.
- Common Collocations
- The most common verb paired with this is 'naru' (to become), as in 'datsuishoujou ni naru.' Another is 'okosu' (to cause/trigger), as in 'datsuishoujou o okosu.'
こまめに水分を摂らないと、脱水症状を引き起こす恐れがあります。
(If you don't take fluids frequently, there is a risk of causing dehydration symptoms.)
Using 脱水症状 correctly involves understanding its role as a noun that describes a condition. Because it is a multi-kanji compound (kango), it carries a somewhat formal tone, but it is used by everyone from doctors to parents. The most important grammatical structure to master is [Person] wa 脱水症状 ni naru, which means '[Person] becomes dehydrated' or 'shows symptoms of dehydration.'
彼はマラソンの途中で脱水症状になった。
(He developed dehydration symptoms in the middle of the marathon.)
Another frequent usage involves the verb 防ぐ (fusegu - to prevent) or 避ける (yokeru - to avoid). When you want to give advice or explain a precaution, you would say 脱水症状を防ぐために... (In order to prevent dehydration symptoms...). This is a staple phrase in health brochures and safety manuals.
- Usage with 'Okosu'
- The verb 'okosu' (起こす) is used when the body 'triggers' or 'brings about' the condition. It sounds slightly more objective or medical. 'Datsuishoujou o okosu kanousei ga aru' (There is a possibility of triggering dehydration symptoms).
脱水症状を防ぐために、スポーツドリンクを飲みましょう。
(Let's drink sports drinks to prevent dehydration symptoms.)
When describing the severity, you can use adjectives like ひどい (hidoi - severe) or 軽度の (keido no - mild). For example, 軽度の脱水症状 (keido no datsuishoujou) is a common way to describe someone who just needs a bit of rest and water, whereas 深刻な脱水症状 (shinkoku na datsuishoujou) implies a life-threatening situation.
- Describing Symptoms
- Often followed by a list of physical signs: 'Datsuishoujou no sain' (Signs of dehydration) like dry mouth or dark urine.
乳幼児は自分の不調を訴えられないため、脱水症状に注意が必要です。
(Since infants cannot report their own discomfort, attention to dehydration symptoms is necessary.)
Finally, in more formal writing or news reports, you might see the phrase 脱水症状に陥る (datsuishoujou ni ochiiru), which means 'to fall into a state of dehydration.' This emphasizes the transition into a negative state. Whether you are writing a medical report or just warning a friend at a summer festival, these patterns will make your Japanese sound natural and precise.
The most common place you will encounter 脱水症状 is in the daily Japanese news during the 'Summer Greeting' (Shochu-mimai) season. From June to September, Japanese TV channels like NHK provide constant updates on the 'Heatstroke Index' (WBGT). Reporters will say, 'Today, X number of people were taken to the hospital due to 脱水症状 and heatstroke.' This makes the word part of the shared seasonal vocabulary of Japan.
ニュースで「多くの高齢者が脱水症状で救急搬送された」と言っていた。
(The news said 'many elderly people were rushed to the hospital due to dehydration symptoms.')
In schools, during Bukatsu (after-school clubs), you will hear coaches yelling to students. They don't just say 'drink water'; they often mention the risk of 脱水症状 to explain *why* students must take breaks. It is used as an educational tool to teach children about body awareness. You might also find this word on the labels of 'Oral Rehydration Solution' (経口補水液 - keikou hosuieki) like the famous brand OS-1, which is sold in every Japanese pharmacy and convenience store.
- Pharmacy and Clinics
- Pharmacists will use this word when recommending electrolyte drinks. 'Kore wa datsuishoujou no toki ni yoi desu' (This is good for when you have dehydration symptoms).
薬剤師さんに、脱水症状の対策について相談した。
(I consulted the pharmacist about measures against dehydration symptoms.)
Another interesting place you hear it is in the context of office health. HR departments might send out emails during heatwaves. These emails contain bullet points on how to spot 脱水症状 in colleagues, such as 'lack of concentration' or 'headaches.' It’s a word that signifies a collective responsibility for health in the Japanese workplace.
- Outdoor Events
- At music festivals like Summer Sonic or Fuji Rock, announcements are made frequently: 'Datsuishoujou ni juubun chuui shite kudasai' (Please be very careful of dehydration symptoms).
フェスの会場では、脱水症状にならないよう繰り返しアナウンスが流れていた。
(At the festival venue, announcements were repeatedly played so that people wouldn't get dehydration symptoms.)
One of the most common mistakes English speakers make when using 脱水症状 is confusing it with the simple adjective 'thirsty.' In English, we might say 'I'm dehydrated' when we just want a glass of water. In Japanese, saying 'Datsuishoujou desu' implies you are actually ill. If you just want a drink, use 喉が渇いています (Nodo ga kawaite imasu). Using the medical term for a minor thirst can sound overly dramatic or cause unnecessary alarm.
× 喉が少し渇いたので、脱水症状です。
○ 喉が渇きました。
(Correct: I am thirsty. Incorrect: I have dehydration symptoms [just because I'm a bit thirsty].)
Another mistake is the confusion between 脱水症状 (datsuishoujou) and 熱中症 (necchuushou). While they are related, they are not synonyms. Necchuushou is the broad category of heatstroke/heat exhaustion caused by heat, whereas datsuishoujou is the specific symptom of water loss. You can have datsuishoujou without being in the heat (for example, if you have the flu), and you can have heatstroke that involves more than just dehydration (like high body temperature).
- Particle Errors
- Learners often use the wrong particle. It is 'datsuishoujou NI naru' (become), not 'datsuishoujou WO naru.' However, you use 'WO' with 'okosu' (to cause).
× 彼は脱水症状をなった。
○ 彼は脱水症状になった。
(Correct: He developed dehydration symptoms.)
Lastly, some learners forget the 'shoujou' (symptoms) part and just say 'dassui.' While 'dassui' is a word, it is more often used as a technical term for 'spin-drying' in a washing machine or the chemical process of dehydration. For the medical state of a person, 脱水症状 is the standard and more natural-sounding term in daily conversation.
- Washing Machine Confusion
- The 'dassui' (脱水) button on a Japanese washing machine means 'spin dry.' Be careful not to tell someone your body is 'spin drying'!
洗濯機の「脱水」機能と、体の「脱水症状」は混同しないようにしましょう。
(Make sure not to confuse the 'spin dry' function of a washing machine with 'dehydration symptoms' of the body.)
While 脱水症状 is the most precise term for the condition, there are several related words you should know to sound more like a native speaker. These vary in formality and specific meaning. Understanding the nuances will help you choose the right word for the right situation.
- 水分不足 (Suibun busoku)
- Literally 'lack of moisture/fluids.' This is a softer, less medical way to say someone isn't drinking enough water. It’s often used in beauty (skin moisture) or general health advice. 'Datsuishoujou' is the result of 'suibun busoku.'
肌の乾燥は水分不足が原因かもしれません。
(Dry skin might be caused by a lack of moisture.)
Next is 熱中症 (Necchuushou). As mentioned before, this is 'heatstroke.' In the summer, people often use these two together or interchangeably in casual talk, but Necchuushou specifically points to the heat as the cause. If someone collapses in winter due to a fever and lack of water, you would only use 脱水症状, not 熱中症.
- 日射病 (Nisshabyou)
- This means 'sunstroke.' It is a slightly older term than 'necchuushou' and specifically refers to getting sick from direct sunlight. Modern medical terminology prefers 'necchuushou,' but you will still hear 'nisshabyou' from older generations.
直射日光を浴びすぎて日射病になった。
(I got sunstroke from being in direct sunlight too much.)
Finally, there is 乾燥 (Kansou), which simply means 'dryness.' This is used for the air, your skin, or a throat that feels dry but isn't necessarily a medical emergency. If you say 'Kansou shite imasu,' people think about the weather or humidity levels, not necessarily that you are about to faint from water loss.
- Summary Table
-
- 脱水症状: Medical/formal state of water loss.
- 水分不足: General lack of fluids (can be mild).
- 熱中症: Heat-induced illness (includes dehydration).
- 喉の渇き: Simple thirst (feeling).
冬は空気が乾燥するので、水分不足になりがちです。
(In winter, the air is dry, so it's easy to lack enough fluids.)
How Formal Is It?
Wusstest du?
The 'datsu' in 'datsuishoujou' is the same 'datsu' used in '脱獄' (datsugoku - prison break). So, dehydration is literally water 'breaking out' of your body!
Aussprachehilfe
- Pronouncing 'su' as a long 'soo'. It should be a short, clipped sound.
- Shortening the 'ou' in 'shoujou'. These are long vowels (shōjō).
- Confusing 'datsu' with 'dasu' (to put out).
- Misplacing the stress on the first syllable like English 'DE-hydration'.
- Merging 'shou' and 'jou' into one syllable.
Schwierigkeitsgrad
Four kanji compound, but the characters are common in B1 level.
Writing '症状' (shoujou) can be tricky for learners due to the stroke count.
Long word, but the pronunciation is rhythmic and consistent.
Very distinct sound, easy to pick out in news reports.

Don't wait until you're sick to use it. Use it in the negative to give advice: 'Datsuishoujou ni naranai you ni...' (So you don't get dehydrated...).
Particle Choice
Remember 'NI naru' for becoming dehydrated. Using 'WO' is a common mistake for beginners.
Summer Survival
In Japan, carrying a water bottle is often seen as a sign of being responsible for your own health to prevent 'datsuishoujou'.
Kanji Clue
Whenever you see '症' (shou), think 'medical condition'. It's in many words like 'shoujou' (symptom) or 'kanshou' (allergy).
Elderly Care
In Japan, 'hidden dehydration' (kakure dassui) is a major topic for the elderly. Mentioning this shows high-level cultural awareness.
News Keywords
Listen for '搬送' (hansou - transport) paired with 'datsuishoujou' in summer news. It means people were taken to the hospital.
Softening the Word
Add 'ppoi' (like) to make it less clinical: 'Datsuishoujou-ppoi' (I feel a bit dehydrated).
Kanji Practice
Break the word into two parts: 'Dassui' (Water loss) and 'Shoujou' (Symptom). It makes it easier to remember the meaning.
Meiji Medicine
Understanding that this is a 'translated' medical term explains its logical, character-by-character structure.
Workplace Etiquette
Asking a colleague 'Datsuishoujou wa daijoubu desu ka?' on a hot day is a very polite way to show you care.
Einprägen
Eselsbrücke
Think of 'Datsu' as 'Detach'. You are DETACHING (脱) the WATER (水) from your body, which leads to SYMPTOMS (症状).
Visuelle Assoziation
Imagine a sponge (the body) being squeezed dry (Dassui) and then turning shriveled and sad (Shoujou).
Word Web
Herausforderung
Write three sentences about a time you felt thirsty using 'datsuishoujou' to describe a more serious state. Try to use the verb '防ぐ' (prevent) in one of them.
Wortherkunft
The word is a 'kango' (Sino-Japanese word) composed of four kanji characters. It entered the Japanese medical lexicon as Western medical concepts were translated during the Meiji era (late 19th century).
Ursprüngliche Bedeutung: Loss of water (脱水) + symptoms (症状).
Sino-Japanese (Kanbun-derived vocabulary).Kultureller Kontext
When talking to elderly people, use the term gently as a concern for their health, not as a criticism of their habits.
In English, people often say 'I'm dehydrated' casually. In Japan, 'Datsuishoujou' is more formal and serious.
